I also have Page Turner, 'Clearly you couldn't put that book down! You read for two hours straight!', and Sleeping In, 'We know you didn't hit the snooze button! You read 5 times between 9am and 12pm'.

Oh, ok, 2 more I can try for.. Though I could have sworn I've read for more than 2 hours in one sitting before.. Does it have to be a single book?
